I love bargain stocks, especially when they're hitting 52-week lows. Still, it can be instructive to also look at stocks that are riding high.

For one thing, they can make good sell candidates. More optimistically, we may be able to find a few companies that can continue their upward climbs.

In this series, I'll search industry by industry for stocks reaching 52-week highs. That way, we'll be able to make a few quick comparisons among semi-related companies.

There are 24 industry groups as defined by the Global Industry Classification Standard (GICS). Energy is one of them.

Below are the top seven companies in this space (by market cap) that are within spitting distance of their 52-week highs.

What's interesting in the energy space is the low earnings multiples, even for these highfliers. There are actually some multiples here that are as low or lower than in the 52-week lows list (click here).

With a heavy reliance on oil in both the highs and the lows list, it makes sense to ask about its viability going forward with all the focus on alternative fuels (though admittedly at lower market caps). Here's an argument for why oil will stick around.
